Working Papers

The WNE Working Papers series has been published by the Faculty of Economic Sciences at the University of Warsaw since 2008.

The WNE Working Papers series provides a fast, open channel for disseminating research conducted at the Faculty of Economic Sciences, University of Warsaw. The papers hosted here are working versions (pre-prints) and may evolve as authors refine their analyses, incorporate feedback, or progress through formal peer-review. What you read is the current version released by the authors, timestamped and assigned DOI/ISSN identifiers to ensure precise citation and version tracking. Copyright remains with the authors, who may, at any time, upload a revised file or add a note directing readers to a later, peer-reviewed publication.

The Working Papers series accepts articles by research employees of the Faculty and publications from conferences organised at the Faculty of Economic Sciences at the University of Warsaw. Articles should be original research papers which have not been previously published, on the subject of economics.

WP510. Two Blind Walls: A Transferable Pedagogical Design for Art-Market Literacy Across Art and Economics Education

This article presents an ongoing pedagogical project at the intersection of economics and art education. It starts from a double blind wall: economics rarely uses the art market as a eaching laboratory, while art education often protects aesthetic judgement from market reductionism. We propose a transferable protocol combining diagnostic questions, valuation tasks, anchoring and signalling treatments, public-art perception probes, and dashboard feedback. Its first implementation uses Wojciech Fangor in Warsaw. The aim is not representative measurement, but a replicable design through which students observe how attention, information, narrative, and market signals shape the encounter with art.

WP498. Behavioral Biases in Stated Preference Valuation of Mortality Risk Reductions: Cost Vector, Anchoring, and Scope Effects

This study investigates how behavioral biases influence stated preference valuation of mortality risk reductions, commonly summarized as the value of a statistical life (VSL). Using a discrete choice experiment (DCE) combined with a contingent valuation double-bounded dichotomous choice and an open-ended follow-up, we elicit individuals’ willingness to pay (WTP) for cardiovascular mortality risk reductions. In a randomized design, we varied the cost attribute across three cost range treatments and manipulated information disclosure and feedback to examine three behavioral phenomena: cost vector effects (whether the range of costs presented affects WTP), scope insensitivity (whether WTP scales appropriately with the magnitude of the risk reduction), and anchoring (whether initial cost cues affect subsequent responses). Our results show that mean VSL estimates can vary by up to ~25% between cost treatments. Furthermore, WTP responses exhibit partial scope insensitivity – larger risk reductions do not proportionally increase WTP – indicating a deviation from theoretical expectations. Importantly, we find no strong evidence of anchoring: neither revealing all attribute levels upfront, nor starting with extreme cost levels, nor providing feedback on quiz questions significantly affected respondents’ choices or WTP. Our findings underscore the need for careful survey design. Even if VSL distributions remain statistically similar across cost frames, substantial shifts in mean magnitudes could be consequential for policy. We call for standardized guidelines on cost attribute selection and survey protocols to mitigate bias, ensuring that stated preference methods yield reliable welfare estimates for health policy decisions.

WP346. Honey, Mugs and Caricatures: anchors on prices of consumer goods only hold hypothetically

We elicit willingness to pay for different types of consumption goods, systematically manipulating irrelevant anchors (high vs. low) and incentives to provide true valuations (hypothetical vs. real). On top of a strong hypothetical bias, we find that anchors only make a substantial, significant difference in the case of hypothetical data, the first experiments to directly document such an interaction. This finding suggests that hypothetical market research methods may deliver lower quality data. Moreover, it contributes to the discussion examining the mechanism underlying the anchoring effect, suggesting it could partly be caused by insufficient conscious efforts to drift away from the anchor.

WP253. Do anchors hold for real? Anchoring effect and hypothetical bias in declared WTP

In two field experiments the authors elicit willingness to pay for a mascara, systematically manipulating incentives to provide the true valuation (hypothetical vs. real) and anchors (high vs. low or high vs. none). Contrary to the key hypothesis, they find no interaction between the two effects: the anchoring effect is not attenuated when decisions actually matter. This finding speaks to validity of hypothetical market research methods and against the use of anchors to reduce hypothetical bias. It also contributes to the discussion of the mechanism underlying anchoring effect, suggesting it is not caused by insufficient conscious effort to drift away from the anchor.
